Why Affairs Happen. As many as 65 percent of men and 55 percent of women will have an extramarital affair by the time they are 40, according to the Journal of Psychology and Christianity.
Nasty-looking scabs might also form over the areas you've scratched, and a bacterial infection may develop. If this is your first bout of scabies, four to six weeks may pass from the time the bugs latch onto you until the time you begin to itch. If you've had scabies before, the wait will last only one to three days.
However, if you have scabies and it is cleared with treatment, and then you catch it again, the symptoms may be slightly different. In such instances the rash and itching develop much more quickly - often within a day or two. This is because the first scabies infestation has already sensitised your immune system.
